Trial Information

Phase II Trial of Weekly Docetaxel (Taxotere) Vs. Weekly Docetaxel in Combination With ZD1839 (Iressa®) As Consolidation Therapy For Metastatic Urothelial Cancer Following Maximal Response To Multi-Agent Chemotherapy

Docetaxel is a drug designed to help stop cancer cells from growing and dividing. ZD1839 is
also a drug designed to block cancer cells from growing and dividing.

Before treatment starts, you will have a complete physical exam. Blood (2-3 tablespoons) and
urine tests will be taken as part of the usual evaluation of liver, bone marrow, blood
clotting ability, and kidney function. A chest x-ray and ECG (test to measure the
electrical activity of the heart) will be done. You will have imaging studies such as a CT
scan of the chest abdomen and pelvis and a bone scan to show the location of current tumors.
If needed, an MRI scan of the brain will be done. This evaluation is considered standard.
Women who are able to have children must have a negative blood pregnancy test. Patients who
have a history of invasive tumors in their bladder, and who have not had a prior cystoscopy,
must have a screening cystoscopy with an EUA (examination under anesthesia), to check the
extent of disease in their bladder. An EUA of the bladder is a standard procedure for
diagnosing and checking the status of bladder cancer.

You will be randomly assigned (as in the toss of a coin) to one of two treatment groups.
Participants in one group will receive docetaxel alone. Participants in the other group will
receive docetaxel plus ZD1839. There is an equal chance of being assigned to either group.
Both you and the study doctor will know to which group you were assigned.

Docetaxel will be given through a catheter (a plastic tube) placed in a large vein in the
chest or arm. The medication will be given over about thirty minutes one day each week for
4 weeks. This will be followed by a 2 week break. The 4 weeks of treatment and 2 weeks
without treatment will be considered one course (6 weeks).

Dexamethasone will be given to decrease the risk of having an allergic reaction to the
docetaxel. In the first cycle, you will receive 3 doses of dexamethasone by mouth every 12
hours starting the night before the docetaxel infusion. If you have no reaction, the
dexamethasone will be decreased in Course 2 to one dose twice on the day of therapy. If
there is no reaction in Course 2, the dexamethasone will be decreased further to 1 dose 1
hour before docetaxel treatment.

ZD1839 is a medication taken by mouth every day without break. Participants in the docetaxel
plus ZD1839 group will take one ZD1839 tablet once a day at about the same time. You can
take ZD1839 with or without food. If you forget to take a dose, take the last missed dose as
soon as you remember, as long as it is at least 12 hours before the next dose is due. If it
is less than 12 hours until the next dose, do not take the dose you have missed.

During treatment, you will have a weekly blood test (2-3 tablespoons) to measure bone marrow
function. A physical exam and blood tests (2-3 tablespoons) will be repeated before each
cycle of treatment. Imaging studies will be repeated at 9 months but may be performed
sooner if you have symptoms that show your tumor may be getting worse. These scans are
considered part of standard routine follow-up.

You will be on study as long as the tumor is not growing at a certain rate and there are no
severe side effects. Therapy will be stopped and you may be taken off study early if one or
both of these things occur. After 6 months, patients can choose to continue therapy if they
wish. At the end of 4 cycles, you will have the option to continue your assigned therapy as
long as it is tolerated and there is no evidence that the disease is getting worse. There is
no maximum amount of time that you can receive treatment on this study.

After the study is complete, follow-up will be arranged at the discretion of your treating

This is an investigational study. The FDA has authorized ZD1839 for research use only. A
total of 90 patients may take part in this study. All will be enrolled at M. D. Anderson.

Inclusion Criteria:

- All patients must have histologic demonstration of metastatic or locally unresectable
transitional cell carcinoma of the urothelium. Minor components (<50% overall) of
variants such as glandular or squamous differentiation, or evolution to more
aggressive phenotypes such as sarcomatoid of small cell change are acceptable.
However, when these atypical histologies are dominant, other treatment approaches may
be appropriate, and such patients are not eligible.

- All patients must have demonstrated some objective response to combination
chemotherapy, and be clinically without progression since this response was
appreciated. In general, patients will have been treated with at least two successive
combination regimens in order to achieve maximum benefit from available chemotherapy.

- Patients who have not achieved a complete response to therapy must have received one
of the chemotherapy regimens outlined in Appendix D prior to receiving consolidation
therapy. Exceptions to this generalization would include patients with a near
complete response to the first regimen given, or patients that are not fit for
aggressive chemotherapy beyond an initially used regimen to which they responded.
Patients must begin "consolidation" therapy within 6 weeks of the end of the last
cycle of induction chemotherapy, and should begin as soon as possible.

- Zubrod performance status of 3 or better. If PS = 3 this must, in the opinion of the
investigator, be secondary to the effects of induction chemotherapy and not the
underlying cancer.

- Patients with a history of cardiac disease, or an ejection fraction (EF) less than
50% at the time of initiation of chemotherapy, must be demonstrated to have an
ejection fraction of at least 40%. In addition, patients having received more than
250 mg/m^2 of doxorubicin during their induction phase, or who have EKG changes since
initiation of chemotherapy must have an EF of at least 45%. Patients with no history
of cardiac disease, a normal EKG and no more than 250 mg/m^2 of doxorubicin are not
required to have an EF measurement.

- Provision of written informed consent.

- Women of childbearing potential must be willing to practice acceptable methods of
birth control to prevent pregnancy.

- Males taking ZD1839 must also use birth control while taking the drug to avoid
pregnancy in their partner.

- International normalized ratio (INR) elevations, bleeding, or both events have been
reported in some patients taking warfarin. Patients taking warfarin with a target INR
of > or = 2, should be monitored regularly (every week in the first cycle, with
further monitoring based on the experience in the first cycle) for changes in
prothrombin time (PT) or INR. Patients on prophylactic low dose warfarin (ie: 1-2 mg
qd for central line thrombosis prophylaxis) do not require frequent monitoring.

Exclusion Criteria:

- Predominantly small cell histology.

- AST or conjugated bilirubin greater than twice the upper limit of normal.

- Serum creatinine greater than 2.5 mg/dL , or a creatinine clearance (either measured
or estimated by Cockcroft formula) of less than 25 mL/min: CLcr = [(140-age) x
wt(kg)]/[72 xCreat (mg/dL)] (Multiply by 0.85 for females)

- ANC less than 1,000; Platelets less than 75,000.

- Prior (lifetime) cumulative exposure to doxorubicin greater than 400 mg/m^2.

- Pregnant and lactating women are excluded. Women of childbearing potential must have
a negative pregnancy test prior to starting therapy.

- An active, or likely to become active, second malignancy.

- Known severe hypersensitivity to ZD1839 or any of the excipients of this product.

- Concomitant use of phenytoin, carbamazepine, barbiturates, rifampin, phenobarbital of
St. John's Wort

- Treatment with a non-approved or investigational drug within 30 days before Day 1 of
trial treatment.

- Incomplete healing from previous oncologic or other major surgery

- Note that there is no requirement for measurable or evaluable disease. Evaluation of
response to therapy is not an endpoint of this trial.

- Prior treatment with therapy which specifically targets the HER family of receptors.

- Patients with peripheral neuropathy > or = to grade 2 should be excluded. Patients
may be included if their neuropathy has resolved to grade 1 by the time they are
registered on the protocol.

- Evidence of any other significant clinical disorder or laboratory finding that makes
it undesirable for the subject to participate in the trial.

- As judged by the investigator, any evidence of severe or uncontrolled systemic
disease (e.g., unstable or uncompensated respiratory, cardiac, hepatic or renal

- Any evidence of clinically active interstitial lung disease (patients with chronic
stable radiographic changes who are asymptomatic need not be excluded).
